converted from the character of'machine' in which the type bars or'otheroperated parts are i mpellcdby means other than the power used indepressing the keys, or force with which the keys are depressed into amachine of that character in which the operration. of the operated partsis eli'ected by the power or force with which the keys are depressed orvice versa.

.The Cahill electric typewriting machine is a representative of thefirst type of machine referred to, while the Remington typewritingmachine is a representative of the second type *of' machine.

The many advantages possessed by a convertible typewriting machine overeither the type of machine in which the operation of the type bars isdependent solely upon power auxiliary to that employed for de-.

pressing the keys or the type of machine in which the operation of thetype bars is. dependent solely upon the power employed for depressingthe key levers, will suggest them selves; butamong others, it ma be wellto mention that a machine ca abe of being converted as described, avois'the objection which is so often urged against the type of machinewhich I have desi noted as of the first class, this objection being thatthe machine is rendered inoperative and useless the moment the auxiliarypower is cut oil for any reason.

Another primary object of the present invention is to provide a simpleand satisfactory electrically operated mechanism for impelling the typebars to the printing point upon the depression of the keys pertainingthereto which includes means for permitting the. return of the type barsand the keys to their initial positions independently of one another.

Another object is to provide a typewriting machine having pivoted typebars with electrically operated mechanism .so positioned that long linkconnections may be interposed between said .bars and the oper-" atinglevers coupled thereto to reduce torsional strain upon said links andthere through lessen the strain upon the type bars which tends'to pullthe same out of their positions.

Other objects of the invention will suggest themselves when't-he same ismore fully explained. v y I VV-ith the objects specifically'set forthand many others in view which will appear and befully appreciated whenthe invention is made clear, the same comprises the novel construct-ion,combination and arrangen ient of parts which will be hereinafterdescribed and particularly pointed out in the claims.

Whilothe' invention is susceptible of vari-l ou's modifications I haveillustrated in the accompanylng drawings what I now con ceive to be thepreferred embodiment of the" same. I

Fig. 6 isa detaiIpers ective view. Fig. 7 is a detail sectional view of amodification of my invention, and, Fig. 8 is a plan view of one of thekey lcvers em- .ployed in this construction .i

The invention is illustrated in thelaccom 'panying drawings, and. willbe'hereinaiter described as embodied in the construction of 'typewritingmachines having pivoted typebars, ascertain subordinate features of theinvention have special reference .to this part'icula'r constructionofmachine, and presents special combinations with certain parts thereof,but it'will be understood that most of the primary features of theinvention are applicable by tion, mechanism is provided for impellingthe typebars to the printing point either by a power auxiliary to thatemployed for deressing the keys or by the power with which the keys aredepressed. In-the particular embodiment of the invention illustrated inthe accompanying drawings and to be hereinafter described, electricityis utilized as the auxiliary power, and the mechanism for utilizing thesame to secure the operation of the machine will first be described, andthereafter will be described the converters and action of the mechanismwhen the machine is converted into one in which the type bars areimpelled solely by force or power employed for depressing the keys. V I1 For the purpose of accentuating the salient features of the inventionin illustratingpbhe same as embodied'in the construction of typewritingmachines hereinbcfore refelrn'edf' parts of, saith;

\ ranged to coact with the vertical arms u pivotally connected at theirlower ends to to, certain of the well-known machines have beeneliminated. i

In these drawings a section of the platen is shown at a, the machineframe at 0, 'two of the type bars pivoted to the upper plate thereofand'depending thereinto at 0, (Z, a buffer ring for the latter at c, andthe keys at The key lever pertaining to each key f, preferably includesa lever proper g, having the key connected directly thereto, and anauxiliary lever 57 having the type bar pertaining to-the key coupledthereto through the intermediary of an adjustable link i.

In order to obtain a. uniform pull upon the type bars in the operationof the machine, the auxiliary linksare preferably pivoted in staggeredrelation to one another, those connected to one set of type barsrepresented by the bar (2, being pivoted approximately centrally ofthemachine at 2, while those coupled to the remaining type bars representedby the bar rZ are pivoted at the rear of the n'iachinc at z.

Pivoted directly to each auxiliary lever y near the frontend of the sameis a bellcra'nlt lever m, the vertical arm of which reacts with themotor frame n to be hereinafter described, while the horizontal arm m ofsaid leverconstitutes the setting or positioning member thereof. Thelevels at, when zontal position, having its side member ivoted at oneend upon a shaft n" supporte in bosses or studs n while the free end ofsaid frame is provided with a contacting surface a, extending entirelyacross the machine and; designed when the frame is drawn down, as willbe described, to strike against the end of the vertical arm m, of thelever m positioned-in the path thereof, and depress the same andtherethrough the auxiliary lever g pertaining to the positioned lever mand through the link 2' actuate the type bar coupled to the lever 9. Oneside member of the motor frame a is preferably provided with an angularextension or depending arm a, winch .is coupled by an adjustable link tothe core of a horizontally arranged'sucking magnet r. The latter isarranged in a normally dead circuit including a generating units,stationary contact point 8', and a universal contact frame If carrying acontact point t, designed to contact with the point 8. The frame 1f,which is pivotally supported, preferably by arms 4: which are themselvespivotally supported by lugs E for a purpose to be hereinafter explained,is provided with a flexible arm extending to the rear of its pivot,carrying the point t and with a cross bar 6'- extending entirely acrossthe machine arthe links 9 which carry the same. An arm u is associatedwith each link g, and the free end thereofjs normally held in arearwardly tilted position by a spring 2/ associated therewith tonormally maintain the shoulder a: of: said arms above and in engagementwith the cross bar 25 and a shoulder 12' formed on said arm inengagement with a lateral extension m" on the free end of the arm of ofthe bell crank lever m associated with the lever pertaining to the leverf] to which the arm a is )ivoted. Each arm n is provided with an 0 setguide opening a designed to receive the end of the lever gpertainingthereto, and each lever is pro vided with a beveled portion, preferablythe end thereof, designed when the lever is depressed, to coact with theend of the bottom wallot' said guide opening to throw the arm npertaining thereto, forward against the tension of its spring u torelease the contact frame and position lever m, as will be hereinafterdescribed.

Upon the depression of one of the keys f, the lever g carrying the sameis depressed, carrying with it the arm upivoted thereto, the latterbeing. in engagement with the cross bar 15 of the universal contactframe t, and with the extension m of the lever massocia ted therewith,and rocks the lever m of the contacting surface m of the motor motorframe at bringing the contacting surface a thereof into engagement withthe end of the arm m of the positioned lever m depressing the latter,and therethrough depressing the lever g, to which said 'positinned leverm is pivoted, thus operatingthe type bar pertainlng to the keydepressed,

through the intermediary of the link connection between said type barand the lever g referred to. In the downward movement of the lever g,the beveled end :12 thereof contacting with the rear edge of the bottomwall of the guiding opening u of the arm it carried by the depressed keylever g throws said arm u forward against the tension of its spring 20and thereby disengages the shoulders 'v and u thereof from the crossbar-t of the universal contact frame t, and the positioned lever m,respectively. As soon as the frame If is released, the same is returnedto its initial position by the spring interrupting the electricalcircuit through the magnet 1' at the points 8', t, thus deiine'rgiz---ing the magnet and permltting the motor frame a to reassume its initialposition under the influence of the spring n The lever m, upon beingreleased 15 atonce restored to .positionby its spring 0 and theauxiliary lever g is restored to position by the spring g associatedtherewith.

The restoration of the parts described to .their initial positions takesplace notwithstanding the fact that the key 7 may be held depressed butas soon as the same is released by the operator, said key and levercarrying the same is restored to position by the spring associatedtherewith. It will be particularly noted that the return of the keyandthe'lever carrying the same, takes place entirely independent of thereturn of the type bar,'and thus should either said key and lever, orsaid type bar stick, it would not effect the return to their initialpositions of the other operating elements.

After the-arm u is thrown forward against the tension of its spring adisengaging the same from the universal contact frame and the extensiona of the lever m, said arm is held out of engagement with said partsuntil the key lever carrying the same is restored to its initialposition, so that should the key lever'become stuck and thus hold downthe arm u, the latter wilianot interfere in any way with the operationof the other keysof the machine.

To hold the-arm out against the tension of its spring at. until thekey-lever carrying the same is restored to its initial position, the

front end or nose '0 of the arm u is designed to enact with the frontend of the part'm or extension m of the latter. preciated that upon thearm a being thrown.

1 out, the lever g" at once returns to its initial position and that thenose u Willremain in engagement with the front .end of said part m orthe extension wa thereof as long as the key lever g remains in itsdepressed position and as a consequence said arm u will be held forwardso as not to interfere with the universal contact frame or the levers mcarried by the other keys.

From the above description, it will be un-- derstood that the movementgiven to the finger key by the operator, serves to shift the arm m intoposition to'be struck by the motor frame and also by effecting the clos-It will be ap-- ing of the circuit, causes the magnet to be actuated.The magnet, whenactuated by the closing of the circuit, effects amovement of the-motor frame which, in' turn,- striking the positionedarm in, moves it and the auxiliary lever, to which it is connected,downward, the movement of the auxiliary lever,

through its connections with the type .bar,

causing the type bar to be actuated. The devices operated by the magnetto thus actuate the type bar, move independently of the movement of thefinger key and return to initial position independently of the movementof the finger key.

As before premised, the present invention contemplates the provision ofmeans for instantly converting the machine from one in which themechanism interposed between the keys and type bars is employed for opcrating the latter when-actuated by the depression of the former bypower auxiliary to that employed for depressing said keys such as hasjust been described, into one in which said mechanism is employed foroperating the type bars by the power or force used in depressing saidkeys. In the construction illustrated in the accompanying drawings, thisobject is attained by merely coupling the levers g to the auxiliarylevers g pertaining thereto, so that the two operate as a singlepart oras one key lever. To this. end, means are provided for maintaining thearms a in their rearward positions with the shoulders '11 thereof inengagement with the upper faces of the extensions m of the levers m, thelatter being thrown for ward to seat said extensions upon the upperedges of the levers g pertaining thereto, as indicated in Fig. 2. r

. As the universal contact frame If is rendered unnecessary in theconverted machine, means are preferably provided for'shifting its crossbar 15 out of the path of the shouls ders n, and as the levers g, g, arecoupled to move in unison, the springs associated with the latter aresuilicient to restore said leversto their initial positions, after thesame are depressed and released, and conscqucntly the springs g arerendered unnecessary and in fact undesirable, and therefore cneans arealso provided for throwing said springs out of operation.

For throwing the levers m forward, and at the same time retracting thecontact frame t, a rocking frame 1, ispi efepably provided, comprisingside arms 4,; pivc tally support d in lugs 2, and a cross bar extendingacross the machine connecting said side arms arranged to the rear of thelevers m to provide, when the machine is arranged to be electricallyoperated, a stop or rest for the arms m. The contact frame t is carriedby the side arms 4, being pivotally connected to the same below thepivotal axis thereof. Any suitable means may be provided for rocking theframe 1 from the position shown in Fig. 1, into the position shown in.Fig. 2,

said'fiame when rocked into the latter tion serving to throw the 3against the arins m of the levers m to hold the latter in advancedpositions, the extensions m of the arms of thereof, coac't-ing with theedges of the levers g to provide stops for said arms and to'retract thecontact frame a to withdraw the bar t thereof out of the paths of theshoulders 12 of the arms in While the bar 3 is preferably made use of tothrow the levers forward to occupy their advanced sitions, said bar canbe dispensed with so far as this function thereotis concerned as thearmsu, when drawn down, aswill bearms m of thelevers m, an eccentricallyjournaled cross shaft '5 is preferably provided. This shaft as shown inthe accompanying drawings in addition to providing means for holdingthearms u in their rear ward positions also provides a stop for arrestingthe upward movements of the levers 9 under the\ ends of the returnsprings thereof. l

To avoid "lost motion in the connection between each lever gand theauxiliary lever arms 10- in lower posit-ions so thatthe shoulj gpertaining thereto, when the machine is set formanual operation only,means/arev provided for normally holding the levers g in a lower planethan that occupied by the same when the machine is set to be operated bypower auxiliary to that employed for; depressing the keys, therebyholding, the

ago-scene 'ders o thereof will be maintained in direct engagement withthe lateral extensions m and the latter maintained in direct engagementwith the ed es of the levers y. To arrest the levers g on the returnthereof in their different positions the cross sha tt 5, before referredto, is preferably provided with two stop surfaces 6, 7. The surface 6also coacts with the links 24, and when said shaft 7 5 turned to bringthe latter surface into action as shown. in Fig. :2, thelevers g areheld in their lowermost return positions, and the arms u are held intheir rearward positions. When the shaft 5 is turned to carry thesurface 6 out of action, as shown in Fig, 1, the arms at are releasedand the surface? is brought into action to provide a stop for the leversg in a relatively higher plane than the stop therefor provided by thesurface 6.

When the machine is arranged to be operated by means auxiliary to thepower employed for depressing the keys, it is desirable that the latterhave but a slight dip,- while when the machine is converted, asdescribed, a relativelydeeper dip of the keys is desired. To this end anadjustable stop for limiting the depression of the keys is desirable,-and in the embodiment of this feature o'ifthe invention hereinafterdisclosed, a stop bar 10, which is common to all 0% the key levers, isprovided, this bar being eocentrically mounted bet-ween the sides of themachine frame, and being provided with two arresting surfaces 10", 10.When the bar is turned, as shown in F ig. 1, the surface 10 performs thefunctionof the stop, and but a slight dip of is provided for.

To obtain a maximuinfdip', the bar 10 is turned to brin the same intothe position illustratedjn ..'ig. 2, in which position the surface it)provides the arresting surface. When the machine is set for manualoperation only, the auxiliary lovers 9 are coupled by the arms a to thelevers g'pertaining to the same, so that the two move as one part, andconsequently upon the depression ofa key, the movement thereof isdirectly transmitted to the type bar pertaining to the same,the'electrically operated mechanism remaining inactive.

In Figt'T a modified embodiment of my I invention is illustrated. Inthis form of the invention, the arms which are utilized to set in actionthe electrically operated incchanism upon the depression of thekeys-pertaining to the same, when the mach-ice is set to be electricallyoperated, and for directly Operating the supplemental levers coupled tothe typebars on the depression of the key levers pertaining thereto,when the machine is set to be manually operated, are supported by anddepended from members employed; for actuating the universal contactframe and for positioning the'push finger; the free I offset p ends ofsuch arms having detachable engagement with the kdy levers with which'the same are associate Referringparticularly to Fig. 7, the key leversare indicated by the letter 9 with each of which a bell crank lever h isassociated, the latter being mounted upon a commoncross-rod it",supported at its ends in opposite sides of the machine frame. To thefree end of the horizontal arm of each lever 72, an arm at is pivotallyconnected, the free end of the latter being provided with a shoulder mdesigned to engage with an offset or an abutment g projecting laterallyfrom the key lever associated therewith. Each key lever is also providedwith an offset finger g in advance of the 'abutment carried therebywhichprovides a guide for the free end of the arm m associated with the same,as will be hereinafter de scribed. Pivoted at its lower end to eachsupplemental lever 7 is a push finger 0 coupled by a link 12 to thevertical arm of the bell crank lever 71 pertaining tothe same; theconnect-ion between said link and the vertical arm of the bell cranklever h being preferably a sliding pivotal one formed by an elongatedslot in the link in which a pin projecting laterally from the end of thevertical arm of the bell crank lever works. The push fingers 0 are, asin the embodiment of my invention first described, held out of the pathof movement of the motor frame 1" which is actuated by the suckingmagnet 8 upon the closing of the normally open electrical circuit whichv includes said magnet, ing unit If, rheostat t? and universal contactframet. The bell crank levers it are normally held up in the position inwhich the same are shown in Fig. 7 by a suitable spring, the free end of.each arm m is held in engagement with the pertaining thereto by aspringm interposed betw'een'thc pivoted en oi. said arm and the bellcranklever 115 carrying thejsame, and the-push fingers 0" are normally heldout of the path of movement of the frame 7 by a spring 0 which isinterposed betw en each of said fingers and the supplemental lever gcarrying the same. Upon the depression of the key lever 9 the bell cranklever h pertaining thereto 'is rocked in the direction indicated by the.arrow, through the interposed arm m The horizontal arm of the bellcranklever coming into cngagementwith the universal the line t, ageneratcontact frame serves to depress the latter 'onsly positions thefinger 0 energized upon the closing and thercthrongh closethe electricalcircuit. The movement of said bell crank lever through the interposedlink p simultanepertaining to the key lever depressed. The i'nagnetbeing of the electrical circuit as before described, actuates thedepressed key lever g vmentof the horizontal If, fixed contact point.

" until the pins, m

the

motor frame T which depresses the supple:

mental lever g pertaining to the key manually operated, through theintermediary of the positioned push the downward movement of thesupplemental lever the inclined end 9 thereof comes into'contactwith alateral abutment m on the arm m which is held down by and serves toforward, disengaging the free end thereof from the oil-set g of saiddepressed lever. As released the bell crank 'lever h is restored toits'initial position by its spring releasing the cont-act frame which isalso restored to its initial position as the electrical circuit isbroken when the'contact frame is released and thus the positioned pushfinger is freed, the latter .being also restored to its initial positionby a spring associated with the same.

As .in the first described embodimentof my invent-ion, to set themachine to be operated manually, is shifted out of the path of itsoperatin members, and the key levers are arrange to be operated inalower plane than the machineis setto be electrically operated. Thecontact frame. as shown herein is eccentrically mounted or pivotallysupported from a rotatable disk It, the operation of which throws thecross-bar of said contact frame, into and out of throw said arm m armsof the bell crank levers It.

As in the preferred embodiment ofmy invention a rocking frame 9" commonto all the key levers g is-provided for limiting the return movement ofthe key levers. When this frame is turned to bring the working face 5/thereof into coaction with the key levers, the latter-are forced down ofthe arms in are seated in recesses in the upper edges of thesupplemental levers g. The supplemental levers are thus, through theinterposition of the arms m and pins in depressed when the key leversare actuated independcntlyof the electrically operated n'iechanism.
